SPECIFICATION forming part of Letters Patent No. 398,054, dated February 19, 1889.

Application filed January 6, 1888.

To all whom it may concern:

Be it known that I, FRANKLIN B. KENDALL, of Tuniwater, in the county of Thurston and Territory of lVashington, have invented a new and Improved Windmill, of which the following is a full, clear, and exact description.

The object of' my invention is to provide a new and improved windmill in which the 1o wind-wheel is turned out of the wind automatically as soon as the wind blows with more than the normal pressure.

The invention consists of rods connected with the spokes of the wind-wheel and with a sliding rod operating on a drum carrying the vane.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then 2o vpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure I is a sectional elevation of my improvement. Fig. 2 is a plan view of the same, parts being in section. Fig. 3 is a rea-r end elevation of parts of my improvement with the vane removed. Fig. 4: is a perspective 3o view of one of the wind-wheel arms, and Fig.

5 is an enlarged sectional plan view of the sliding rod and its connections on the line n of Fig. l.

My improved windmill A is provided with a suitably-constructed tower, B, in which is mounted to rotate the vertical hollow shaft C, provided near its lower end with a bevel gear-wheel, D, meshing into a bevel gearwheel, D', secured to the driving-shaft D2, 4o connected in any suitable manner with the machinery to be driven. Near the upper end of the hollow main shaft C is held to rotate a frame, E, on which is mounted the windwheel F and the vane G.

The wind-wheel F is secured on a hollow shaft, H, mounted to rotate in a bearing, E', secured on the frame E; and on the inner end of said hollow shaft H is secured a bevel gearwheel, H', meshing into al bevel gear-wheel,

low shaft O. The wind-wheel F is provided with a'suitable number of radial spokes, I, held between flanges H3, formed on the hollow shaft H. On the front and rear of the iianges H3 are secured short spokes J, pro- 55 vided at their sides next to the spokes I with inclines J', as illustrated in Fig. l. Bolts pass through the flanges H3, the spokes I, and the spokes J, thus securing the parts firmly together. The spokes J extend only a short v6o distance outward in line with the spokes I, so that when the latter are bent inward or outward a suitable distance they rest'against the inclines J of the said spokes J, thus preventing a furtherbending of said spokes I.

Each spoke I of the wind-wheel F carries a number of blades, K, increasing in length toward the outer end of the wheel and eX.-v tending in a straight line at one end and in an inclined line atthe other end, as illus: 7o trated in Figs. l and 4. A small space interi venes between two successive blades, K, and

the spokes I maybe connected with each other at their vouter ends, if deemed necessary. In front, near the upper end of each spoke I, is securedan eye, I', connected with one end of an inclined rod, L, extending radially and outward from the wheel F, and having its inner end formed into an eye, L', engaging a ring, N', held on a block, N, secured to the 8o outer end of a rod, O, passing' through the hollow shaft H. The block N is provided with grooves Ni, into which iit the eyes L of the rods L, so as to prevent said rods L from being displaced on the block N, as is fully shown in Fig. 5.

The inner end of the rod O is provided with a ball, O', fitted loosely into a cavity, P', formed in a slide, P, reciprocating in axial line with the wheel F in a suitable guide, Q, 9o secured to the frame E. The cylinder P is nearly filled with oil, against which operates kthe ball O. On one end of the slide P is secured one end of a rope, R, extending to and wound around a drum, S, secured to avertical shaft, T, mounted to rotate in a suitable oilbox, E2, fastened on the frame E. On the vertical shaft T and on the drum S is secured H2, secured to the upper end of the main hol- 5o 11h11 radial lforl e1l :'11'111 (1 11|' thc vanetf, which latter thus inrns with the vertical shaft 'l and with 11111,1 said 1lrn1n bf.. On the other end of the slide l. ,is secured one end 111' a rope, R', also passing 11v11ra111l woundaround the druin 5,111 an opposite 1li1'c11li11n, however, 11'1'11111 the 1111111121, llt will be s111111 that when the slide l moves forward or backward 111111 V1'111111,R or R, Vis unwound lr11111 the drinn S, wl1il1,1 111e 11111111' 11111111 is wound 1111 1h11 111111111. (')n 11111 1l1'111n H is also l'as1en111l 11111101111 111 a 111111511, whi0h passes over a 111111115211", secured io the l'rainc 1C, :11111 111011 111111 rope 1,1 extends downward :11111 carries 1111 its lower end a weight, 1'?, ,1111' 111111|110rl1alancing the vane G. A11- other 111110, V, is wound. and secured by one 11nd 1111 the 111111111 S in an opposite direction to 111e 1111110 1v and passes over a pulley, V, held in suitable bearings on the iraine E above the upper opening ol 111e hollow shaft C, and carries on its lower 1,11111 a weight, Y2, which can be drawn downward b v a lever, \V, mounted 11n the tower 13.

The operation is as follows: The vane G is held in position bv the counterbalancing- 'weights 1,1'2 and Y?, so that the wind coniing in an,\11flircction acts 11n the vane G, and thus 1 turns the traine E accordingl to the direction oi the wind, 11'11111'111'1111v the wind-wheel F is iln'own in thc1 wind. The latter acts on the blades l( 111E 111e wheel l in the usual manner, and 11111111111w rotates the wind-wheel F, so that its shalt ll, byineans ol the bevel gear-wheels ll and il?, imparts a turning inotion to the inain hollow shalt C, connected in any suitable inanner with the n'lachiner)v 1o be driven. ll" the wind increases bevond a normal. pressure, the force oli' thc wind causes a backward bending' of the spokes l', so that the rods L exert a 11ressur11 against the block N in the direction ol the arrow 11', whereby the rod O is moved inward and causes the slide P to slide in the saine direction in its guide Q. This inward sliding' 111 the slide P rotates the drinn 11,1 means 1,11' 111111 rope R which exerts :1 pull 11n the drinn bl, so that the vane G, se- 0 urcd 111 the said drinn, is held in position by 11111 l'orec ol.' the wind, thereby causing', on account ol' 111e said inovenient of thc 111111111, the

wheel 11 111 inove 11111 ol' the wind, so that the speed 11i' the wind wheel is decreased. As soon as the pressure oi' the wind moderates, the spokes l again sprinli'orward and assume 11111111111111111111 position, whereby the rod O is caused 111 sli1l11 outward in the inverse direC- tion ol' 1h11 arrow 11', 111111111111' pulling' the slide P111111511111111111 1111siti1'1n and again rotating 1110 drinn S until the vane (1 isagain in aparallel lin1,1 with the axis olf the wind-wheel F.
